The EJ20X and EJ20Y are open up deck engines whereby the cylinder walls were supported at the a few and nine o’clock positions. It came having an aluminium alloy block with ninety two mm (3.

Lots of have an additional intake air temperature sensor from the throttle human body. Its purpose continues to be mentioned but not completely clarified.

These EJ20Gs can be discovered through a tab on the right area on the block half plus a smoother surface area. The EJ20G ongoing to become the principal engine while in the WRX wagon having an automatic transmission from 1996 right until 1998; then, it had been replaced through the EJ205.
